Trek of the devil's church is one hiking route of Kuhankuono hiking routes. It's name comes out of this certain type of rock formation that is called devil's church. In this trek there is one of them. Also along this trek is this cave called luolakallio that some want to spend the night, if they are on longer hike.
This is the only part of Kuhankuono hiking routes that has some really harder parts. There are some steeper rocks to climb and decent so don't go to this one without good shoes.
This route is bit over 10km long, and over 20km if you back same route to your car etc. Many of these routes are ones that go more or less round route and you end up back where you started. This is one of those which are different ones.
On first leg I did the filming and taking pictures, so it became longer (as always) on Sport Tracker. On the way back the distance was lot more real, but battery of my phone died just before I got back to starting point (had too many calls during that day).
Even this was the hardest one of these treks it still was one of the best ones also.
